Oct 1, 2025

October 2025 (2025-10) focused on strengthening CI reliability, code quality, and maintainability for cipherstash/encrypt-query-language. Delivered a targeted set of CI/tooling enhancements and a codebase cleanup, reducing build friction and improving long-term maintainability. Key commits include adding SQLx lint checks, enforcing cargo fmt, ensuring rustfmt in CI, and establishing a reliable Rust toolchain via setup-rust-toolchain, as well as a cleanup pass that removed outdated comments. Temporary disabling of non-critical SQLx linting was used to preserve green CI during tooling rollout. These changes enable faster PR feedback, lower regression risk, and smoother onboarding for new contributors. Technologies demonstrated: Rust, SQLx, CI tooling, cargo, rustfmt, setup-rust-toolchain.
